Joomla/PHP/MySQL expert needed to integrate a piece of existing code into an extension

I have some modifications that need to be done on my existing Joomla extension. I need someone who is very good at joomla/PHP /mySQL to integrate code from one extension to another and add a menu item for a group of registered users. The code already exists, it is a matter of adding it to the right place. As part of your bid, please include at least 3 links to Joomla/PHP/mSQL projects you have completed. If you haven’t done any similar projects, please don’t bid.
